Ford hasn't recorded a gain in U.S. market share since 1995, when it held 25.7 percent of the market.

Also Wednesday, the American Family Association and several conservative leaders pressured Ford to reverse its decision to continue running advertisements in gay publications, criticizing the automaker's role in "the cultural war."

Ford said in December that it planned to stop advertising its Jaguar and Land Rover luxury brands in gay publications to reduce marketing costs.

But several gay rights groups complained about the decision, and Ford changed course after meeting with the groups, saying it would advertise all of its eight brands in gay publications.
